The actor, 59, admitted that Islamic prayer "got into his spirit" while filming in Istanbul.

He told The Sun, "The call to prayer happens five times a day, and for the first week, it drives you crazy, and then it just gets into your spirit, and it's the most beautiful, beautiful thing."

He added, "There are 4,000 mosques in the city. Some are just stunning, and it really makes me think about becoming a Muslim."

Neeson was raised in Northern Ireland as a devout Roman Catholic and was named after the local priest. But the star -- whose wife, Natasha Richardson, died aged 45 in a skiing accident in 2009 -- has spoken about challenges to his faith.

He said, "I was reared a Catholic, but I think every day we ask ourselves, not consciously, what are we doing on this planet? What's it all about? I'm constantly reading books on God or the absence of God and atheism."

His latest movie, "The Grey," about an oil-drilling team that crashes in freezing Alaska, is released in the US and the UK on Friday.
